Cisco switch 3550

Hi,
When I try to configure VTP domain name on my 3550 switch, the option for the domain name is not in the list of the options. Could someone advise please?
DLS1(config)#vtp ?
file Configure IFS filesystem file where VTP configuration is stored.
if-id Configure interface as the preferred source for the VTP IP updater
address.

you can try on this in vlan data base go to enabale mode then give the
command vlan database then there you can set vtp command transperent server
or client as you wish
vlan database
vtp tranparent or as you wish
